Online pH Detector

Online pH detectors measure the hydrogen ion concentration in a solution by generating a potential difference between a glass electrode and a reference electrode, enabling real-time monitoring of liquid acidity or alkalinity. They are used in process control applications such as water treatment and chemical reactions to ensure stable operations.
Selection
When selecting, consider the corrosion resistance of the electrode material, the temperature and pressure adaptation range, the matching of the protection level with the on-site environment, the compatibility of the signal output type with the existing system, and the convenience of calibration and maintenance.
